SULKY-HARROW.

SPECIFICATION forming part of Letters Patent No. 307,977, dated November 11, 1884.

Application filed March 24, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that we, A. F. PACK and ED- WIN FRENCH, both of Emporia, in the county of Lyon and State of Kansas, have invented a new and Improved sulky-Harrow, of which the following is a full, clear, and exact description.

Our invention consists of improved apparatus for raising up the harrows to suspend them from the axle when required, and to lower them to the ground again, the object being to simplify the appliances, improve the efficiency of the same, and to lessen the labor of operating them, as will be hereinafter fully described and specifically claimed.

Reference is tobe had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of our improved harrow, and Fig. 2 is an elevation in rear View.

We pivot a handlever, a, having a halfpulley rim, 7), to the axle c of the sulky at d over the center of each half e of the harrow and connect one end of a cord, f, of suitable length, to the lever, as at h, in any approved way, extending the cord therefrom around the pulley b to the outside of the harrow, and around a sheave, g, thereat; thence directly upward to the axle, to which we connect the cord ati by passing it through an eye-stud, or by any other approved means; and from i we extend the cord to the inside of the same part of the harrow and around a sheave, k, there-at, and up to the lever on the pulley b, where we fasten the other end of the cord as at Z, so that the working of the lever will draw alike on both sides of the part of the harrow to which it is connected for raising and lowering the same, and the cord will work with but very little friction by running on the pulley b and the sheaves g 70, said cord being stationary in the connection with the axle at t. V

The levers a are fitted with suitable racks m, to hold them in position. In this case the levers are set with the pulleys b inward, and the cord is connected to the axle over the outer sides of the harrow to work the levers for raising the harrow by pushing them outward from the seat it; but it will be readily seen that the arrangement may be reversed by turning the pulleys outward and connecting the cords to the axle over the inner sides of the two divisions of the harrow, to raise the harrow by pulling inward, if desired.

We propose to joint the two parts 6 of the harrow by joint-bars 0, connected to the ends of the respective parts by stud-pivots p, on one or both of which the bars 0 may be shifted, by means of different holes q, to adjust the harrow for varying the distance of the two parts from each other, which is often required.

For hitching the harrow to the sulky, so that said harrow may be raised and lowered readily, we connect the two parts with the tongue 8 about even with the front end of the harrow, and where the evener t is attached to to said tongue by a tensionrod, a, to each part, using rods of sufficient length to extend back along the harrow about a quarter of its length, or thereabout,-which makes a simple contrivance for hitching the harrow to the sulky in a way enabling it to be swung up by the levers a. p

In practice we will connect the rods u adjustably to the harrow for shifting the connection toward and from the end of the harrow, as may be required.

To adapt the harrow for working on both sides of rows of growing plants, we will substitute arched rods 0 for the straight form herein represented.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination, with a sulky and a harrow, of the lever a, pivoted to the sulky, and provided with a pulley-rim, eyebolt, or analogous device, 2', also on the sulky, as shown, sheaves g 76 on opposite sides of the harrow, and a cord, f, passing from the lever under sheave k, through eyebolt 1', under sheave g, and back to the lever, substantially as set forth.

2. The combination, with the sulky and the jointed harrows e, connected thereto in front of their centers by the rods 14 u, of the sheaves k g on the opposite sides of the harrows at or near their centers, lever a, secured to the sulky, and the cord f, secured to said lever and passing through the eyebolt and sh eaves, substantially as shown anddescribed.
